example 1

[0013] Example 1. According to the proportion in formula 1, take citric acid (containing crystal water) and grind it for later use. Crush calcium chloride (containing crystal water) with another grinder. Then add zinc powder and iron powder with a fineness of less than 100 mesh and grind and mix them for later use. Mix the mixture of crushed calcium chloride (containing crystal water), zinc powder and iron powder with crushed citric acid (containing crystal water) according to the ratio in formula (1) before use. Mix it now, take 2g~3g from it, put it into a compound paper bag and seal it for use. For example, crush 1.5kg of citric acid (containing crystal water) first. Take 0.6kg of calcium chloride (containing crystal water) and grind it with another grinder. Mix 0.2kg of zinc powder and 1.2kg of iron powder for later use. Before use, grind the mixture of crushed citric acid (containing crystal water), calcium chloride (containing crystal water), zinc powder, and iron po...

example 2

[0014] Example 2, according to the ratio in formula 2, take citric acid (containing crystal water) and grind it for later use.

[0015] Crush calcium chloride (containing crystal water) with another grinder. Measure the iron powder with fineness less than 100 mesh for later use. Before use, mix the crushed citric acid (containing crystal water) with the crushed iron powder and calcium chloride (containing crystal water) according to the ratio in formula (2). Mix it now, take 2g~3g from it, put it into a compound paper bag and seal it for use. For example, crush 1.25kg of citric acid first. Take 0.6kg of calcium chloride (containing crystal water) and crush it with another crusher. Then crushed 1.25kg citric acid (containing water of crystallization), 0.6kg of calcium chloride (containing water of crystallization) crushed, and 1.25kg iron powder with a fineness less than 100 orders are ground and mixed evenly together. Take 2g~3g from it and put it into a composite paper ba...

Abstract

The invention provides an antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package, wherein the antioxidant hydrogen sustained-release agent comprises zinc powder, iron powder, citric acid and calcium chloride based is mass ratio according to the quality guarantee period requirement of food. (1) The formula (mass ratio) of the antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package with quality guarantee period less than 3 months is that the ratio of zinc powder to iron powder to citric acid (containing crystal water) to calcium chloride (containing crystal water) is 0.2:1.2:(1-1.5):(0.5-0.7); (2) the formula (mass ratio) of the antioxidant hydrogen sustained-release agent for oil-containing food in gas-filled package with quality guarantee period less than 6 months is that the ratio of iron powder to citric acid (containing crystal water) to calcium chloride (containing crystal water) is 1.25:(0.75-1.25):(0.5-0.75).The hydrogen sustained-release agent has the advantages of hydrogen is released slowly; a part of hydrogen is consumed through reaction, and redundant hydrogen can go out of packages to be released; and potential safety hazards caused by accumulation of hydrogen are overcome. Iron, zinc, calcium chloride and citric acid react stably, do not generate odor and harmful air, and are harmless to humanbody.

Description

technical field [0001] The invention relates to a food fresh-keeping packaging technology, in particular to an anti-oxidation hydrogen slow-release substance for oil-containing food used in air-filled packaging and a processing method. Background technique [0002] Such as silicon-calcium-carbon composite deoxidizer, which can absorb oxygen and slow down the oxidation of food substances. It can prolong the shelf life of food, and can also play a certain role in preventing oil from rancidity, preventing oxidative browning of meat, and preventing the loss of vitamins in food. The commonly used reaction principles of deoxidizers include iron powder oxidation (iron system), enzyme oxidation (enzyme system), ascorbic acid oxidation, and photosensitive dye oxidation. Most of the deoxidizers currently used are based on the oxidation reaction of iron powder. This iron-based deoxidizer can be made into a bag and put into a package to reduce the oxygen concentration to 0.01%. It is...
